Walker's Low Catmint is sterile, so says most reputable places on the web. I've had mine for 4 years and have never found a seed. But I have seen on GW where a couple of people say they have found just a few seeds. My plant has gotten slightly bigger in 4 years, I believe that is from it doing its own stem propagation. Good Luck

If you have any of these seeds, please let me know and let's trade! Thanks :) Carol

You're welcome "girl" for not thinking I got TOO detailed. I tend to do that alot..lol. For #1 - the color in pics is very true (well, depending on your monitor, I guess). I'd defintely say more purple than blue. Paler, like Lavender color, I guess (dont have lavender but have seen it) but even then, more intense or deeper in color (bear in mind...that's my soil, my zone, etc). #2 - Because I leave most everything alone until spring (unless it requires fall pruning)...I'm partial to leaving all dead stuff for birds, etc. So not sure if my taste is like yours. Past two falls/winters I left it alone since it lived for so long yet kept the same shape. We have very mild winters but did have a couple freezes and yet, nothing got brittle and only lost about half the flowers. Of course it turned brown (lol) but basically looked like the same plant, only dead. Don't know if that's what you're looking for...but if you're looking for something to fill up space during winter, he definitely did the job. And I'd say it's the perfect plant to leave alone until you mow it down before bulbs come up. BTW, just for zone comparison -- I'm couple blocks from beach but not sandy soil. Have 6-8" good soil before clay, summers are humid as hell, over 100 some days, and often no rain for weeks (I do water during those times). Let me know what you figure out !! Bonnie (aka Brit)

I have never tried winter sowing nepeta but it does root real easy if you dip the cuttings in rooting hormon. I have a bunch of Six Hills Giant (my favorite!)growing in a pot right now.
